Check the dimensions of your washing machine against the available space.
Historical and Practical Reasons
The first automatic washing machine that resembles the type of machine we use today was invented in 1978.
Simply put, there was a need to incorporate this new invention which required plumbing, drainage and electricity into our existing homes. The room which offered the most practicality in terms of existing utility connections was the kitchen. Another benefit is that the kitchen typically offers direct access into the garden so that any washing can be hung out to dry.
For many, the washing machine in the kitchen format has remained popular to this day simply owing to familiarity. This is especially the case as most kitchens now also have ventilation, which is also a requirement in modern times.
